started property
Started is when the recording began, as the media server reports it: its own started_at, verbatim and unconverted. LiveKit's egress service sets that field from UnixNano, and a conversion this side cannot check against the running server would be a number that looks right and is wrong by a factor of a billion. 0 means it has not started.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
int? started;
